0.77 Ct. Alexandrite from Brazil

This beautiful transparent alexandrite from The Natural Gemstone Company is a rare and refined choice for the collector who demands natural color change, clarity, and cut. It weighs 0.77 carats, and it is fashioned into a cushion shape with a mixed brilliant cut that maximizes flash and depth. The measurements are 6.43 millimeters by 5.18 millimeters by 2.97 millimeters, and the polish has been graded excellent. The color wonder of this stone is its green to purple change, with vivid color intensity that reads as a lively green under fluorescent lighting, and as a rich purple under incandescent lighting. The clarity is very slightly included when evaluated at eye level, which means the inclusions are minor and do not compete with the stone s strong color and brilliance. Importantly, there has been no enhancement, this alexandrite is natural and untreated, and it hails from Brazil, an origin noted for producing fine color change material that offers both character and value.

When you compare this stone to others on the market, several practical advantages become clear. Many alexandrite looking stones are laboratory grown, or they receive enhancement treatments to improve clarity or color, and those interventions change both the rarity and the long term value. Compared with large but heavily treated stones, this 0.77 carat alexandrite delivers authentic color change and untreated provenance, which collectors and discerning buyers prefer. The mixed brilliant cut is superior to flat step cuts for this material because it amplifies the color change with well placed facets that return light dynamically, this makes the gem appear larger and more lively than a comparable weight with a less sophisticated cut. Compared with color change garnets and synthetic color change sapphires, this alexandrite offers a subtler and more valuable shift between green and purple, and the vividness of the hues in both lighting conditions sets it apart from paler or less responsive stones. The cushion outline offers a classic modern balance of softness and presence, so it presents well in rings, pendants, and bespoke designs, adding versatility that tight round or overly ornate cuts may not.

The inclusions in this alexandrite are part of what makes it special, acting as natural fingerprints that confirm origin and authenticity, and that add unique character to each viewing. Graded as very slightly included at eye level, the inclusions are delicate and unobtrusive in everyday wear, and under magnification they tell the story of the stone s formation deep within the earth. These tiny internal features can appear as pinpoint crystals, faint silk like veils, or very small healed fissures, and they catch light in a way that contributes to the gem s depth and scintillation rather than detracting from it. Compared with stones that have been clarity enhanced by filling, laser drilling, or glass diffusion, the natural inclusions in this alexandrite remain stable over time, and they are considered positive attributes by many collectors because they make the gem one of a kind. In practical terms these small inclusions mean the gem is unmistakably natural, they help gemologists and buyers trace the stone to its geological source, and they provide an organic texture within the depths of the color change, enhancing the visual drama when the stone transitions from green to purple under different light sources.

Choosing this alexandrite from The Natural Gemstone Company means selecting a piece that balances rarity, integrity, and wearable beauty, and its specifications rival many higher priced or treated alternatives. The vivid color change, excellent polish, and mixed brilliant cushion cut create a gem that will catch the eye in any setting, and its untreated Brazilian origin adds provenance that most mass market pieces cannot claim. For an engagement ring, a signature pendant, or a museum inspired creation, this stone offers a striking color story without sacrificing clarity or durability, and its modest carat weight is compensated by proportionate dimensions and an efficient cut that maximizes optical performance. We recommend classic closed bezel settings or prong mounts that allow light to enter and highlight the change, and we advise routine gentle cleaning with warm soapy water and a soft brush to preserve polish. As with all fine natural gemstones, the presence of subtle inclusions affirms the piece s authenticity and will become part of the narrative you wear and pass down. At The Natural Gemstone Company we present this alexandrite with detailed imaging and transparent descriptions so you can choose with confidence, and this gem stands as a superior choice for those who value natural color change, untreated origin, and expert cutting over common treated or synthetic alternatives.
